Abstract

Black crowberry(Empetrum nigrum var. japonicum) is a low and creeping evergreen shrub that generally reaches 10∼20cm in height and occurs only in Mt. Halla in South Korea. This study was conducted to investigate black crowberry's spatial distribution type and to estimate its genetic diversity and spatial genetic structure. The study plot was 2,400m2 (60m×80m) in size, and a total of 189 samples were observed in the plot. Aggregation index(R=0.828) revealed that spatial pattern of this population was aggregated. Even though black crowberry is a rare and regional species, Shannon's diversity index(I=0.531) indicated that the level of genetic diversity was higher than those of plant species with similar ecological characteristics. Spatial autocorrelation analysis using Tanimoto distance showed that the genetic patch was founded within 10m. So as to find out the genetic relationship of clumps and genets, we compared ISSR genotypes of all individuals within the population. A total of 187 unique genotypes were observed from 189 individuals, and most of clumps seemed to be separate genets
